Benefits of technology

The invention is a triggering device that can synchronize the operations of multiple photographic devices, including cameras and flash units. The device allows for cross-brand and cross-manufacturer use, which improves flexibility and adaptability for users and reduces costs. The invention also provides a computer-readable medium carrying instructions for implementing the method.

Problems solved by technology

In contrast, the exiting products in the market allow synchronization only when the camera and the flash unit(s) are of the same system format, i.e. devices which are manufactured by exclusive manufacturers, which leads to a very limited choice of devices for the users and typically higher costs.

Abstract

The invention provides a method and a device for synchronizing a flash unit with a camera. The method comprises steps of communicating a first encoded signal from the camera to a trigger; decoding the first encoded signal by the trigger to form a first decoded data; encoding the first decoded data to form a second encoded signal, and communicating the second encoded signal to the flash; wherein the first and the second encoded signals are of different system-specific formats. The device comprises an input for communicating a first encoded signal with the camera; a first decoder for decoding the first encoded signal to form a first decoded data; a first encoder for encoding the first decoded data to form a second encoded signal; and an output for communicating the second encoded signal with the flash; wherein the first and the second encoded signals are of different system-specific formats.

Description

FIELD OF THE INVENTION[0001]The invention relates to a device and a method for synchronizing a plurality of photographic devices. Particularly but not exclusively, the invention relates to a triggering device for synchronizing the operation of multiple flash units with a camera during image acquisition and the method thereof.BACKGROUND OF THE INVENTION[0002]Various photographic triggering systems have been developed to assist communication between a camera and their corresponding flash units for a synchronized operation during image acquisition, especially during outdoor shootings when effective synchronization among multiple remote flashes and the camera is critical.[0003]A number of new developments have been applied to improve the triggering devices in the market. For example, the Through-The-Lens (TTL) flash metering technology has been applied to photographic triggering systems to provide automation in lighting control such as exposure adjustment. A number of wireless technolog...
